Properties
- High-temperature resistance: Can sustain prolonged use in high-temperature environments exceeding 1700°C.
- Mechanical strength: Vickers hardness (HV) is approximately between 1100 and 1200.
- Flexural strength: 500-1000 MPa.
- Fracture toughness: 5-10 MPa·m^1/2.
- Thermal shock resistance: Thermal expansion coefficient is about 10×10^-6/K, effectively resisting thermal stress caused by rapid temperature changes, reducing the risk of cracks and damage.
Application Industries
- High-temperature kiln furniture and furnace components: Ideal material for manufacturing kiln furniture, crucibles, and furnace linings. These components can withstand high temperatures and thermal shocks, extending their service life.
- Mechanical parts and tools: High strength and wear resistance make Mg-PSZ suitable for producing cutting tools, pump components, seals, and bearings.
- Medical devices: Excellent biocompatibility and high strength make it suitable for medical applications such as dental implants and joint replacement materials.
- Electronic and electrical components: Used in the manufacturing of insulators, substrates, and other high-performance electronic components.
- Aerospace: Employed in the production of high-temperature components such as nozzles and turbine blades.
